Blurring techniques are methods used in photography and digital imaging to soften the details of an image. This can create a dreamy effect, reduce distractions, or emphasize certain elements by making the background less distinct. Common types of blurring include Gaussian blur, motion blur, and lens blur, each serving different artistic or practical purposes. In graphic design, blurring can help focus attention on a subject by diminishing the clarity of surrounding areas. It is also used in photo editing software to enhance images, create depth, or simulate effects like bokeh, where out-of-focus points of light appear as soft circles.
